Understanding the 2V Ford Cleveland

Before diving into the specifics of an upgrade package, it's essential to appreciate the 2V Ford Cleveland. This engine, known for its robust construction and strong torque characteristics, was a staple in many Australian Ford vehicles during the 1970s and 1980s. The '2V' designation refers to the two-valve cylinder heads, which, while capable, can often be a limiting factor in achieving peak performance compared to their 4V counterparts. However, with the right modifications, the 2V can be transformed into a potent powerplant.

What's Inside a Comprehensive 2V Cleveland Upgrade Package?

A quality upgrade package is designed to work synergiously, ensuring that each component complements the others for optimal results. Here's a breakdown of the typical inclusions in a premium 2V Ford Cleveland upgrade package:

1. High-Performance Carburettor

The carburettor is the heart of the fuel delivery system, and upgrading from a stock unit to a performance-oriented model can make a dramatic difference. A typical package will feature a Holley Street HP double pumper carburettor. You'll usually have a choice between a 650 CFM or 750 CFM unit, depending on your engine's specific build and intended use. Key features of these carburettors include:

• Capacity: 650 or 750 CFM (Cubic Feet per Minute) – a larger CFM rating generally supports higher horsepower levels. The choice depends on your engine's modification level and desired RPM range.
• Street HP Design: Engineered for excellent street performance, offering a balance of power and drivability.
• Double Pumper: This refers to the presence of accelerator pumps on both the primary and secondary throttle shafts, providing a quicker throttle response and better fuel delivery under acceleration.
• Square Bore Pattern: This is the standard mounting pattern for many performance intake manifolds.
• Race Bowl: Features a more robust fuel bowl design, often with a dual fuel inlet for improved fuel flow and stability.
• 4-Corner Idle Mixture Adjustment: Allows for precise tuning of the idle mixture for each cylinder, leading to a smoother idle and better fuel economy.
• Polished Finish: Adds a touch of visual appeal under the bonnet.

2. Performance Intake Manifold

The intake manifold is responsible for distributing the air-fuel mixture to the cylinders. An aftermarket performance manifold can significantly improve airflow and power delivery. A common inclusion is the Weiand X-Celerator intake manifold. This manifold is specifically designed for V8 engines and offers a broad powerband, typically ranging from 1,500 to 7,000 RPM, making it versatile for both street and occasional track use. Its design promotes efficient airflow and helps the engine breathe easier, especially at higher RPMs.

3. Quality Gasket Set

Proper sealing is crucial for any engine component, especially the intake manifold. A package will include a high-quality Fel-Pro printo seal intake gasket set. Fel-Pro is renowned for its durable and reliable gaskets. The 'print-o-seal' technology often incorporates a rubber or silicone bead that provides a superior seal, preventing vacuum leaks and ensuring optimal performance and longevity.

4. Braided Fuel Line and Fittings

Fuel delivery needs to be robust and reliable to support the increased demands of a performance carburettor. The package often includes a -6 braided fuel rail. Braided lines are stronger and more resistant to heat and abrasion than standard rubber hoses. You'll typically have a choice of finishes, such as all silver or silver hose with black fittings, allowing you to match the aesthetic of your engine bay.

5. Carburettor Spacer

A phenolic carburettor spacer is a small but often beneficial addition. While not always pictured, it's a common inclusion. Phenolic spacers are excellent insulators, helping to reduce heat transfer from the intake manifold to the carburettor. This can prevent fuel percolation (boiling in the fuel bowl) and maintain a more consistent fuel temperature, leading to better performance, especially in hot weather.

6. Fuel Pressure Gauge

Maintaining the correct fuel pressure is vital for carburettor performance. Too much or too little pressure can lead to poor running conditions, hesitation, or even engine damage. A fuel pressure gauge, often available with a black or white face to suit your dashboard or engine bay aesthetics, allows you to monitor this critical parameter accurately.

7. Throttle Cable Bracket and Return Springs

To ensure proper connection and operation of the carburettor's throttle linkage, a billet throttle cable bracket is usually included. These brackets are often crafted from billet aluminium for strength and appearance. They come complete with a dual return spring setup, which provides reliable throttle return to idle, an essential safety feature for any performance vehicle.

8. Carburettor Mounting Hardware

The final pieces of the puzzle are the carburettor mounting studs & nuts. These ensure the carburettor is securely fastened to the intake manifold, preventing leaks and vibrations.

Customisation Options

A good upgrade package offers a degree of customisation to suit your specific needs and preferences. In this case, you'll typically be able to:

• Select Carburettor Size: Choose between 650 CFM and 750 CFM based on your engine's build.
• Specify Fuel Line Finish: Opt for all silver or silver hose with black fittings.
• Choose Throttle Cable Bracket Colour: Select from silver, black, blue, or red to complement your engine bay's theme.

It's important to clearly specify these choices during the checkout process to ensure you receive the exact components you desire.

Benefits of the Upgrade Package

Installing this comprehensive package can yield significant improvements:

• Increased Horsepower and Torque: The combination of a high-flow carburettor, performance intake manifold, and improved fuel delivery will naturally lead to a substantial power increase across the RPM range.
